I don't even know if I'm pregnant yet (only maybe 12 DPO, but definitely TTC), but for the past two days, I have on several occasions felt such a strong wave of nausea that I had to actually RUN to the bathroom.

With my DD, I never had morning sickness, so this is unexpected.

For any women who DO experience morning sickness, how early in your pregnancy did you start feeling it, and what was it like?
